An annual tax formerly laid on the English nation for maintaining forces to oppose the Danes, or to furnish tribute to procure peace. It was at first one shilling, afterward two, and at last seven, for every hide of land except such as belonged to the church.
At a subsequent period, when the Danes became masters, the Danegelt was a tax levied by the Danish princes on every hide of land owned by the Anglo-Saxons.
